The cards use the UHS‑I bus with U1 (UHS Speed Class 1) and Class 10 speed ratings.
They are promoted for Full HD video recording and still photography, including RAW and JPEG images.
The U1 / Class 10 rating guarantees a minimum sustained write speed of 10 MB/s.
Listings include 8 GB, 16 GB and 128 GB cards; one product description also references a card family with capacities from 32 GB to 256 GB.
Descriptions mention waterproofing (one listing cites JIS IPX7), temperature tolerance (one lists −13 to 185 °F), shock resistance, x‑ray protection, static protection, and resistance to bending or vibration.
Some listings include memory card holders; a microSD listing specifically notes a microSD‑to‑SD adapter with a write‑protect switch for use in SD‑compatible devices.
Descriptions target devices that support the UHS‑I bus—specifically digital cameras, DSLRs and camcorders—and at least one microSD listing calls out Android smartphones and tablets.
